ABSTRACT:
A method of densifying glass-composite structures using a superplastically deformed foil to partially encapsulate a glass-composite part and a part holding die. The die and part are contained in a rigid box held in a press. The foil is deformed over the die and part. Heat and pressure are applied to the die and part, through the rigid box, to soften the glass matrix of the part and to cause the glass to flow into the voids of the part.
